Frequency Response

DB10 has a frequency range of 38-180 Hz whereas DB4S has a frequency range of 10-350 Hz. With a minimum frequency of 10Hz, the DB4S can go significantly deeper on the low side and provide stronger bass compared to the DB10's min frequency of 38Hz.

Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Subwoofer class in our database.

Cabinet Type

The Fluance DB10 has a Bass Reflex type cabinet. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs. On the other hand the B&W DB4S have Acoustic Suspension type enclosure. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported designs.

Physical Specs

Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Fluance DB10's and B&W DB4S's external dimensions. Fluance DB10 has external dimensions of 406.0 x 302.0 x 399.0mm ( 16 x 11-7/8 x 15-11/16inch) whereas B&W DB4S has external dimensions of 375.0 x 362.0 x 434.0mm ( 14-3/4 x 14-1/4 x 17-1/16inch) .

Fluance DB10 is 60mm narrower and 35mm less deeper than B&W DB4S but it is also 31mm taller.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited. The base surface area of the Fluance DB10 is approximately 1205.0cm2 / 186.8inch2 and base area of the B&W DB4S is approximately 1571.1cm2 / 243.5inch2. The DB10 requires 23% less surface area than the DB4S which gives it a small advantage on placement in tight spaces.

Weight Comparison

The weight of a subwoofer may become an important factor if you need to move and reposition the unit often to find the optimal positioning, also known as 'Subwoofer Crawling'. The Fluance DB10 weighs 11.20kg / 24.6lbs and the B&W DB4S weighs 26.05kg / 57.3lbs. This makes the DB4S 133% heavier than the DB10.
